Description

  The present invention relates to an eccentric rotary power generator.

Power generation devices are roughly classified as conventionally known ones, and various large-scale power generation devices such as wind power generation devices, steam power generation devices, hydroelectric power generation devices, wave power generation devices, and solar power generation devices have been developed.
In recent years, the global warming problem has surfaced, and carbon dioxide emission regulations have been exclaimed. As a clean energy technology to cope with this, the above-mentioned solar cells, wind power generation and the like have been noticed and developed and are currently in operation, but the current situation is that they are not widely used due to problems such as cost and maintenance.

Accordingly, the present inventors have developed a new device that utilizes gravity on the earth and efficiently converts it into rotational energy for power generation.
Invented in the course of this development is an eccentric rotating power generator introduced in Patent Document 1 to Patent Document 3.
This eccentric rotary power generator is driven by a natural driving force such as wind power, steam power, hydraulic power, wave power, etc., using a rotational drive shaft for power generation rotation as drive energy, and it has an eccentricity with greatly improved electrical energy conversion efficiency. It is a rotary power generator.
As described in Patent Documents 1 to 3, the eccentric rotary power generator is displaced in a horizontal direction by a predetermined amount from the center position of the bowl-shaped perfect circle magnet ring rail and the true circle magnet ring rail. A rotation drive shaft that is horizontally disposed perpendicular to the position, and a permanent magnet guided member that is mounted on the rotation drive shaft via an eccentric rotation guide shaft mechanism and can be circulated in a non-contact state along a magnet ring rail; The main component is a fly weight attached to the permanent magnet guided body.
The vertical circular magnet ring rail has a permanent array of guide permanent magnets with the same magnetic pole aligned on the outer peripheral surface side and the inner peripheral surface side, and the magnetic poles have a repulsive relationship with the permanent magnet guided permanent magnet. Face to face.
In this way, the permanent magnet type guided body can follow the inner and outer peripheral sides of the magnet ring rail in a non-contact state and can run around. The eccentric rotary shaft mechanism is slidable along the rotational radial line of the rotary drive shaft and supports the permanent magnet guided at intervals of a rotation angle of 180 degrees. By rotating the eccentric rotation shaft mechanism with the rotation drive shaft and rotating the fly weight attached to the permanent magnet type guided guide eccentrically, a rotation moment is applied to the rotation drive shaft and it is rotated with a light load to generate electricity. is there.

This eccentric rotary power generator reduces energy loss once the rotary drive shaft is rotationally driven with a slight force using hydraulic power, wind power, wave power, other natural energy, or fine electric power obtained therefrom. Ensuring efficient power generation is the biggest goal.
However, the rotational resistance of the permanent magnet type guided around the magnet ring rail is reduced, the sliding resistance between the permanent magnet type guided and the eccentric rotating shaft mechanism cooperating with the fly weight, and the eccentric rotation. The contact type and non-contact type have been devised to equalize the axial force distribution during rotation applied to the shaft mechanism, both of which have the problem of uniform rotation resistance and axial force distribution. As a result, the results were advanced to the next development stage.

  FIG. 4 shows rotational angle positions of an eccentric rotating shaft mechanism 01, a permanent magnet type guided 05, and a fly weight 06 which are guided and rotated by a magnet ring rail 03 in which fixed permanent magnets 03m are arranged in a conventional eccentric rotating power generator. FIG. 2 is a schematic explanatory diagram showing a rotational moment generation region applied to a rotational drive shaft for rotating in a target left rotation direction (→ forward rotation direction) and a region in which a rotational moment is generated in the reverse rotation direction.

  In the eccentric rotary power generator, the magnet ring rail 03 is a perfect circle as is apparent from FIG. 3, and the rotational center 02 position of the eccentric rotary shaft mechanism 01 is set to the horizontal diameter line of the perfect circle magnet ring rail 03. As shown in the figure, for example, as shown in the figure, the eccentric rotary shaft mechanism 01 is linear, and on both sides thereof, that is, at a position with a rotation angle interval of 180 °, permanently. When a flyweight 06 of equal weight W including the magnet type guided 05 is arranged and the rotary drive shaft of the eccentric rotary shaft mechanism 01 is rotated, the pair of permanent magnet type guided 05 and its flyweight 06 are There is a region MO that exists in the single arc portion 03-1 on the rotation center 02 side of the eccentric rotary shaft mechanism 01 from the vertical line 07 passing through the circle center 03c of the magnet ring rail 03. Outside this region MO, this is a region where a rotational moment is always applied to the rotational drive shaft in order to rotate in the intended left rotational direction. The region MO is a region sandwiched between two positions 3031-3031 and 3032-3032 where the left and right rotational moments are in the same neutral state, and a pair of permanent magnet guided 05 and its fly weight 06 are located in this region. During this time, a reverse rotation load in the right rotation direction in the figure is always applied to the core 02 of the rotation drive shaft, causing an energy loss, resulting in a deceleration state, causing a large rotation fluctuation and being unstable.

JP 2010-35393 A Japanese Patent Laid-Open No. 20100-26881 JP 2010-96170 A

  In the present invention, except that the rotational moment when the fly weight supported by the eccentric rotating shaft mechanism 01 is on the vertical diameter line becomes zero, the positive axial force in one rotation direction is always maintained and the deceleration due to the reverse rotation load is performed. The present invention provides a novel eccentric rotary power generator capable of stably obtaining a smooth continuous rotation state with minimal rotation unevenness due to rotational inertial force, while minimizing the state and energy loss caused thereby.

The basic technical configuration of the present invention that satisfies the above problems is as follows (1).
(1) A vertical magnet ring rail 100-2 in which permanent magnets 111 for guide having the same magnetic poles aligned along the outer peripheral surface side and the inner peripheral surface side of the ring frame 110 are fixedly arranged, and an axial core 301. The rotational drive shaft 2 disposed horizontally and perpendicular to the position displaced from the central position 102 of the horizontal diameter line 101 of the magnet ring rail 100-2 by a predetermined amount in the horizontal direction, and the rotational radial line of the same rotational drive shaft 2 The eccentric rotary shaft mechanism 300-2 that is slidable along the 303 and mounted thereon, and both magnetic pole faces of the permanent magnet 111 of the magnet ring rail 100-2 supported on both sides of each eccentric rotary shaft mechanism 300-2. On the other hand, it is composed of a permanent magnet type guided guide 203 which holds the magnetic pole surface of the traveling permanent magnet 201 facing each other in a repulsive relationship, and a fly weight 202 attached to the permanent magnet type guided guide 203. The relative positional relationship between each of the permanent magnet type guided guides 203 supported by the eccentric rotating shaft mechanism 300-2 and the fly weight 202 is shifted evenly by a predetermined angle, and the eccentric rotating shaft mechanism 300- is driven by the rotary drive shaft 2. In the eccentric rotary power generator that applies a rotational moment to the rotary drive shaft by rotating 2 and rotating the permanent magnet type guided 203 and the fly weight 202 eccentrically,
The axial center position of the rotary drive shaft 2 is displaced to a position that is 1/3 to 3/5 of the horizontal diameter line 101 of the rotating magnet ring rail 100-2, and the magnet ring rail 100-2 has the horizontal diameter described above. A semicircular portion 100a in which a perfect circle with a diameter line on a straight line 302 passing through the rotational drive shaft 301 is divided into two around the diameter line, and a long axis is a horizontal diameter. A composite endless ring (100-2) in which the minor axis is placed on the line 101 and the minor axis is the diameter line of the semicircular part 100a and the semi-elliptical part 100b divided into two around the minor axis is combined, and a plurality of the eccentric rotating shaft mechanisms An eccentric rotary power generator characterized in that the relative positional relationship between each permanent magnet type guided guide 203 supported by 300-2 and the fly weight 202 is shifted to a predetermined uniform rotation angle.

  In the eccentric rotary power generator having the above-described configuration according to the present invention, when the rotary drive shaft 2 is rotated in the positive rotation direction (arrow) even a little by the eccentric rotary shaft mechanism 300-2, the rotational center of the rotary drive shaft 2 is rotated. Rotational moment applied to the shaft core 301: kg. m is 0 only when the center of gravity of the permanent magnet type guided guide 203 including the fly weight 202 exists on the vertical diameter line 302, and is high to rotate in the normal rotation direction (arrow) at any position except this. Maintains a positive axial force to reduce the deceleration state due to reverse rotation load and the resulting energy loss to a very small level, and to achieve a stable continuous rotation state without stopping due to a slight rotation unevenness due to rotational inertia force. It is done.

  This rotational operation causes a slight change in the rotational speed of the rotary drive shaft 2 when there is a single eccentric rotary shaft mechanism 300-2, but a plurality of eccentric rotary shaft mechanisms 300-2 are attached to the rotary drive shaft 2 and If the relative positional relationship between the mechanisms of the permanent magnet guided 201 is shifted by a predetermined angle evenly, the rotational moment applied to the rotation center axis 301 of the rotary drive shaft 2 is made high and equalized to prevent rotational speed fluctuations. A smooth continuous high-speed rotation state can be stably obtained.

FIG. 3 is a side cross-sectional explanatory view showing Example 1. The cross-sectional positions of arrows AA, BB, CC, and DD attached to each eccentric rotary shaft mechanism 300-2 shown in FIG. 1 arrive on the vertical diameter line 302 of the magnet ring rail 100-2. FIG. It is side surface explanatory drawing which shows typically the structure of the magnet ring rail 100-2 of FIG. It is a simplified explanatory view showing the state of the rotational moment applied to the rotary drive shaft in the conventional perfect magnet ring rail

  The present invention will be described in detail by the following examples.

An embodiment of the present invention is shown in FIGS.
1 to 3, the basic configuration of the magnet power generation device of this example is the same along each outer peripheral surface side and inner peripheral surface side of a pair of ring frame bodies 110 that are fixedly supported in a cage in parallel with the stand. A vertical magnet ring rail 100-2 in which permanent magnets 111 for guides aligned with magnetic poles are fixedly arranged, and an axial core 301 from the center 102 position of the horizontal diameter line 203 of the magnet ring rail 100-2 to a predetermined amount in the horizontal direction. A rotary drive shaft 2 disposed horizontally at right angles to the displaced position, and an eccentric rotary shaft mechanism 300-2 slidably mounted on the same rotary drive shaft 2 along its rotational radial line 303; A permanent magnet supported on both sides of each eccentric rotary shaft mechanism 300-2 and held so that the magnetic pole surface of the traveling permanent magnet 201 faces the magnetic pole surface of the permanent magnet 111 of the magnet ring rail 100-2 in a repulsive relationship. The permanent magnet type guided guide 203 includes a guided weight 203 and a fly weight 202 attached to the permanent magnet type guided guide 203 via an appropriate support mechanism, and is supported by the plurality of eccentric rotating shaft mechanisms 300-2. And the offset weight shaft 202 are arranged so as to be shifted by a predetermined angle and the eccentric rotary shaft mechanism 300-2 is rotated by the rotary drive shaft 2 to rotate the permanent magnet type guided guide 203 and the offset weight 202 eccentrically. Thus, a rotational moment is applied to the rotational drive shaft. The fly weight 202 may be integrally formed.
In this magnet type power generator, the position of the axis 301 of the rotary drive shaft 2 is shifted to the position of 1/3 to 3/5 of the horizontal diameter line 101 of the rotating magnet ring rail 100-2, so that the magnet ring rail. Reference numeral 100-2 denotes a semicircular portion 100a having a vertically symmetrical shape with respect to the horizontal diameter line 101, and an ellipse having a long axis on a straight line 302 passing through the rotation drive shaft 301 divided into two around the long axis. A plurality of the eccentric rotary shaft mechanisms 300- are formed by combining the ellipse whose short axis is on the straight line 302 passing through the rotational drive shaft 301 with the semi-elliptical part 100b divided into two around the short axis. The relative positions of the permanent magnet type guided guides 203 supported by 2 and the fly weights 202 are arranged so as to be evenly shifted by a predetermined angle of 60 degrees.
The magnet ring rail 100-2 has a vertically symmetrical shape with respect to the horizontal diameter line 101 due to the configuration of the semicircular part 100a and the semielliptical part 100b, and is tangent to the arc part intersecting with both ends of the horizontal diameter line 101. Becomes a vertical line, and a tangent to an arc portion intersecting with both ends of the vertical diameter line 302 becomes a horizontal line, which is a semicircular part 100a and a semi-elliptical part 100b between the horizontal diameter line 101 and the vertical diameter line 302. 100b is formed by a multipoint curve and / or a continuous arc of a parabola or a combination thereof.
Thus, the ratio of the short axis to the long axis of the semi-elliptical part 100b is 0.8: 1 to 1.2: 1.
By setting this ratio and the position of the axis 303 of the rotary drive shaft 2 to the position of 1/3 to 3/5 of the horizontal diameter line 101 of the rotary magnet ring rail 100-2, the eccentricity by the rotary drive shaft 2 is achieved. The rotation of the rotary shaft mechanism 300-2 and the rotation of the fly weight 202 are smoothly performed, and an even and large rotational moment is generated in the rotary drive shaft 2.
In other words, when these ranges are removed, the rotation trajectory of the fly weight 202 is extremely flattened vertically or horizontally, and the rotational resistance of the permanent magnet type guided 203 with respect to the fixed permanent magnet 111 in the magnet ring rail 100-2 increases. Smooth rotation and sufficient acceleration cannot be obtained.
With this configuration, the above-described excellent operational effects are exhibited.
The permanent magnet type guided 203 has a pair of U-shaped support arms 203a rotatably attached to both sides of the fly weight 202 so that the shaft 203s can be rotated, and the U-shaped support arm 203a has one or a plurality of the travels. The permanent magnet 201 is supported and arranged with a predetermined distance from the fixed permanent magnet 111 of the ring rail.

<Details of each component>
1. The permanent magnet 111 for fixing the magnet ring rail 100-2 and the traveling permanent magnet 201 of the permanent magnet type guided guide 203 are permanent magnets having a renewal life determined from a practical magnetic attenuation life to a range of general common sense. is there.

2. The shape of the permanent magnets 111 and 201 is a rectangular parallelepiped, a cube, a circular pack, a polygonal pack, or a curved shape appropriately formed from these.

3. The magnet ring rail 100-2 is provided as a single shape formed by the semicircular portion 100a and the semielliptical portion 100b as described above or in parallel as in the example of FIG. 2 and the example of FIG. Each of the pair of magnet ring rails 100-2 has a pair of ring frame bodies 110 facing each other and a fixed permanent magnet 111 sandwiched between the frames. The fixed permanent magnets 111 are arranged in the circumferential direction of the ring frame 110. The magnetic poles S and N are aligned on the ring outer peripheral side and the ring inner peripheral side.

4. The arrangement of the permanent permanent magnets 111 in the magnet ring rail 100-2 is arranged at the center between the inner and outer circumferences of the ring frame 110. For example, the magnetic poles on the inner circumferential side of the ring of the permanent permanent magnet 111 are aligned with the N poles. The magnetic pole on the ring outer periphery side is aligned with the S pole. In this case, the permanent magnet facing the permanent magnet 201 of the permanent magnet type guided 203 facing the magnetic pole on the inner peripheral side of the ring of the fixed permanent magnet 111 is set to N pole, and the permanent magnetic pole facing the magnetic pole on the outer peripheral side of the ring of the fixed permanent magnet 111 is used. The magnetic poles of the opposing surfaces of the permanent magnet 201 and the fixed permanent magnet 111 of the permanent magnet guided 203 are repelled by making the facing magnetic pole of the permanent magnet 201 for traveling of the magnet guided 203 the S pole. Make a relationship.

5. The eccentric rotary shaft mechanism 300-2 rotates around the rotation center axis 301 of the rotary drive shaft 2 orthogonal to the intersection of the horizontal diameter line 101 and the vertical diameter line 302, and the permanent magnet type guided shaft A smooth rotation speed can be obtained by supporting a pair of the outer weight 203 and the fly weight 202 movably in the rotational radius direction 303 at equal angular intervals of 180 degrees. In the example of FIGS. 2 and 3, a cylindrical slide guide 304 is attached and fixed to the rotary drive shaft 2, and the shaft portions 303a and 303b are supported so as to be movable in the rotational radius direction. A hollow square pipe (other rectangular, H-shaped, T-shaped, I-shaped, etc. beam-shaped ones) is made into a double-sliding expansion / contraction structure, and is slidable / contracted by a bearing support mechanism or a sliding support mechanism. It is possible.
The shaft portion may be separated into a pair of parallel shaft portions, one of which is fixed on one side to the fly weight 202 and the other is fitted on the fly weight 202 so as to be slidable.
As shown in FIGS. 1 and 2, the slide guide 304 is provided with four eccentric rotation shaft mechanisms 300-2 at a rotation angle interval of 45 degrees.
Therefore, as shown in FIGS. 1 and 2, the pair of magnet ring rails 100-2 guide all the four pairs of permanent magnet type guided guides 203 of the eccentric rotating shaft mechanism 300-2 for four machines.

6. A permanent magnet type guided 203 has a pair of U-shaped support arms 202 pivotally attached to both sides of the fly weight 202 so that the shaft 204 can rotate, and the U-shaped support arm 202 has one or more permanent magnets. 201 is supported and arranged at a predetermined interval with respect to the fixed permanent magnet 111 of the ring rail 100-2, and the permanent magnet type guided 203 is slidable in the rotational radius direction 303 via the fly weight 202. It is supported and rotates along a pair of both ring frame bodies 103 of the magnet ring rails 100-2 in a non-contact state.

8. Although not shown in the figure, the rotary drive shaft 2 is connected to a rotary drive device and a power generator using natural energy such as hydraulic power and wind power. However, various devices generally attached are not limited and should be installed as appropriate. It's okay.
For example, providing a flywheel at an arbitrary position where the rotary drive shaft 2 does not bend is effective because it has a function of rotating the eccentric rotary shaft mechanism more smoothly and obtaining power by the rotational force with high efficiency. .

9 and the magnet ring rail 100-2 has an inertial force accompanying the rotation of the eccentric rotating shaft mechanism 300-2, because the distribution in the circumferential direction of the ring is slightly deviated toward the eccentric side. As the structure, for example, in the case of the high strength heat insulating F303P fiber reinforced plastic or the magnet ring rail 100-2, the ring frame 110 is made of stainless steel, and a donut-shaped reinforcing plate is integrally attached to the side surface.

10 and FIG. 2 show each eccentric rotating shaft mechanism 300-2 on the diameter line 302 (vertical diameter line) of the semicircular part 100a which is also the short axis of the semielliptical part 100b of the magnet ring rail 100-2 shown in FIG. It is sectional explanatory drawing at the time of the fly weight 202 coming.
In this example, since the shaft portion 301 of each eccentric rotating shaft mechanism 300-2 is linearly supported in parallel with the guide 304, each fly weight 202 is moved from the middle portion of the magnet ring rail 100-2 to the left side of FIG. 1), FIG. 2 (2), and right side FIG. 2 (3), FIG.
In FIG. 2, each eccentric rotation shaft mechanism 300-2 is positioned near the fly weight 202 in order to position each fly weight 202 at an intermediate portion between the pair of ring frames 110 of the magnet ring rail 100-2. It is shifted.
As described above, when the magnet ring rail 100-2, the permanent magnet type guided guide 203, the eccentric rotating shaft mechanism 300-2, and the fly weight 202 shown in FIGS. Installed with respect to the rotary drive shaft 2, the fly weights 202 between the sets are more smoothly arranged by setting the relative rotation angle position to a rotation angle equal to 360 degrees divided by the number of fly weights 202. A uniform and large rotational moment is generated in the rotational drive shaft 2.
For example, when two sets of the sets shown in FIG. 1 and FIG. 2 are installed on the same rotation drive shaft 2, the number of fly weights 202 is 16, and the relative rotation angle position is 22.5 degrees.

  Although the embodiments of the present invention have been described above, it is obvious that there are examples in which various combinations and simplifications of the examples are arbitrarily selected in addition to these examples, and these show the technical idea of the present invention. It is not something that can be removed.

Industrial applicability

  The eccentric rotary power generator of the present invention reliably obtains excellent effects as described above. For this reason, once the rotary drive shaft is rotationally driven with a slight force using hydraulic power, wind power, wave power, other natural energy, or the fine electric power obtained therefrom, an efficient power generation with reduced energy loss is ensured. Can be secured. As a clean energy, it is possible to easily obtain maintenance-free power generation at low cost, and it is a power generator widely used in various power supply industries and widely used in the spread industry.
